Kinsey knows that 8x7 is 56 use the drop down menu to show how she can use this knowledge to find 8x6 a.-1 b. +1 c.-6 d.-8 e.+8
so
8 times 7 vs
8 times 6
8 times 7 is 8 more than 8 times 6
therefor 56 is 8 more than 8 times 6
so minus 8
answer is D
The difference between 87 and 86 is one 8 less, so it would be d, or -8.
